Hi,If its an offline account wich you are playing, then look for the downloaded data from the expansions and copy them into the data-folder of fallout 3, then best get the fallout 3 mod manager (fomm) from fallout3nexus.com/ .Don't know if anyone else has the same problem that the original manager from the launcher doesn't remind the aktive mods.If it doesn't help, well, then use Voodoo.
